A remark on quasiconformal mappings on Carnot groups. [PDF]

open access: yesMichigan Mathematical Journal, 1994
A. Koranyi and M. Reimann informed me that a result of theirs on the theory of quasiconformal mappings on the Heisenberg groups contradicted inequality (20.17) in my monograph [Strong rigidity of locally symmetric spaces, Ann. Math. Studies, No.

Morrey estimates for subelliptic p-Laplace type systems with VMO coefficients in Carnot groups

open access: yesElectronic Journal of Differential Equations, 2016
In this article, we study estimates in Morrey spaces to the horizontal gradient of weak solutions for a class of quasilinear sub-elliptic systems of p-Laplace type with VMO coefficients under the controllable growth over Carnot group if p is not too

Local Monotonicity and Isoperimetric Inequality on Hypersurfaces in Carnot groups

open access: yesBruno Pini Mathematical Analysis Seminar, 2010
Let G be a k-step Carnot group of homogeneous dimension Q. Later on we shall present some of the results recently obtained in [32] and, in particular, an intrinsic isoperimetric inequality for a C2-smooth compact hypersurface S with boundary @S.

Optimizing a machine learning design of dielectric properties in lead-free piezoelectric ceramics

open access: yesMaterials & Design
Designing lead-free piezoelectric ceramics with tailored electrical properties remains a critical challenge for various applications. In this paper we present a novel methodology integrating Machine Learning (ML) and optimization procedures to fine-tune ...

The p-Laplace equation in a class of Hormander vector fields

open access: yesElectronic Journal of Differential Equations, 2019
We find the fundamental solution to the p-Laplace equation in a class of Hormander vector fields that generate neither a Carnot group nor a Grushin-type space. The singularity occurs at the sub-Riemannian points, which naturally corresponds to finding

Performance of plant-produced RBDs as SARS-CoV-2 diagnostic reagents: a tale of two plant platforms

open access: yesFrontiers in Plant Science
The COVID-19 pandemic has underscored the need for rapid and cost-effective diagnostic tools. Serological tests, particularly those measuring antibodies targeting the receptor-binding domain (RBD) of the virus, play a pivotal role in tracking infection ...

c horizontal convexity on Carnot groups

open access: yes, 2010
Given a real-valued function $c$ defined on the cartesian product of a generic Carnot group $\G$ and the first layer $V_1$ of its Lie algebra, we introduce a notion of $c$ horizontal convex ($c$ H-convex) function on $\G$ as the supremum of a suitable family of affine functions; this family is defined pointwisely, and depends strictly on the horizontal
